Abstract
The utility model relates to a connecting device for hollow pipes. The connecting device consists of multiple hollow pipes, wherein the upper end and lower end of each hollow pipe are respectively provided with a through groove; one connecting piece is arranged between every two hollow pipes; each connecting piece consists of a retaining block and two hollow connectors protruding from the upper end and lower end of the retaining block; each connector is internally provided with an elastic long block device; and a clamp block of an elastic clamp block device extends out of the outer end surface of the connector and is matched with the through groove. After the hollow pipes are sleeved on the connectors, the hollow pipes can be firmly connected and have less possibility of dropping due to the clamping role of the elastic clamp blocks on the connectors; and the connecting device is very convenient to use.
Description
Technical field:
The utility model relates to a kind of hollow tubular connection set.
Background technique:
Various easy wardrobes or Tool Cabinet with hold in the thing frame, hollow bushing commonly used is as skeleton.The diameter at these sleeve pipe two does not wait, and during use, that casing diameter is less one is inserted bigger one of another root casing diameter, promptly adopts the mode of planting each other to couple together between the sleeve pipe.The sleeve pipe of this structure comes off easily, often occurs having loaded onto this root pipe in the installation process, the situation that root pipe but falls down.Even after skeleton intactly builds, also must extreme care when mobile, otherwise the phenomenon of falling apart will appear easily.
Summary of the invention:
The purpose of the utility model just is to provide to the deficiency on the existing sleeve structure a kind of easy for installation and hollow tubular connection set of being connected firmly.
For realizing above-mentioned purpose, the utility model is made up of the more piece hollow tubular, and the two ends up and down of hollow tubular have groove; Be provided with a connection piece between per two joint hollow tubulars; This link by a gear block be convexly set in gear block up and down the hollow connecting head at two ends form, be provided with elasticity fixture block device in the connecting head, the fixture block of elasticity fixture block device stretches out in the exterior edge face of connecting head and cooperates with groove; After fixture block snapped in groove, hollow tubular got final product socket and is fixed on the connecting head.
Further; Described elasticity fixture block device is made up of fixture block, spring and screw; The front end of fixture block stretches out from the groove that is opened on the connecting head exterior edge face, and an end of spring withstands on the ear end face of fixture block, and the other end then withstands on the front-end face with the screw that cooperates with tapped hole; Tapped hole and groove lay respectively at the both sides of connecting head, and its position is corresponding each other.
Further, described hollow tubular and connecting head all are cylindric.
Further, the anterior end surface of said fixture block is an inclined-plane, and the front side of its upper-end surface or lower end surface also is an inclined-plane.
Through said structure, after hollow tubular was inserted on the connecting head, because the screens effect of the elasticity fixture block on the connecting head, hollow tubular can couple together securely, is not prone to obscission, uses also very convenient.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is done further explanation:
Accompanying drawing 1 is the three-dimensional structure diagram of the utility model
Accompanying drawing 2 is the user mode figure of the utility model
Accompanying drawing 3 is the three-dimensional structure diagram of the connecting head part of the utility model
Accompanying drawing 4 is the three-dimensional structure diagram at another visual angle of connecting head part.
Embodiment:
See accompanying drawing 1, shown in 2; The utility model comprises: more piece cylindrical core barrel 10 (wherein two joints only draw among the figure); The two ends up and down of hollow tubular 10 have groove 11, and per two joints are provided with a connection piece 20 between the hollow tubulars 10, this link 20 by a gear block 21 be convexly set in gear block about in the of 21 the hollow connecting head 22 at two ends form; Be provided with elasticity fixture block device 23 in the connecting head 22, the fixture block of elasticity fixture block device stretches out in the exterior edge face of connecting head 22 and cooperates with groove 11.
See that accompanying drawing 3 is with shown in the accompanying drawing 4; Elasticity fixture block device 23 is made up of fixture block 24, spring 25 and screw 26; The front end of fixture block 24 stretches out from the groove 221 that is opened on connecting head 22 exterior edge faces; One end of spring 25 withstands on the ear end face of fixture block 24, and the other end then withstands on the front-end face with the screw 26 that cooperates with tapped hole 222, tapped hole 222 and groove 221
Lay respectively at the both sides of connecting head 22, its position is corresponding each other.The anterior end surface of fixture block 24 is an inclined-plane 241, and the front side of its upper-end surface (connecting heads 22 of gear block 21 upper ends) or lower end surface (connecting heads of gear block 21 lower ends) also is an inclined-plane 242.
When assembling is used, at first hollow tubular 10 is set on the connecting head 22 and toward the direction of gear block 21 and presses.When the tube wall of hollow tubular 10 is run into the inclined-plane 242 on fixture block 24 upper-end surfaces or the lower end surface, produce a transverse component fixture block 24 is pressed in the groove 221.After hollow tubular 10 is set on the connecting head 22 fully (gear block 21 is run in the lower end surface that is hollow tubular 10), rotate
Hollow tubular 10 makes groove 11 on the hollow tubular 10 go to the position corresponding with fixture block 24, and one 24 is promptly ejected groove 11 under the elastic force effect of spring 25, hollow tubular 10 is blocked, thus hollow tubular 10 is fixing.When taking off hollow tubular 10, hollow tubular 10 is rotated to the direction that the inclined-plane of fixture block 24 front ends 241 tilts, the sidewall of the groove 11 on the hollow tubular 10 is to tiltedly
Certainly; The hollow tubular 10 of the utility model and connecting head 22 except be designed to cylindric, also can be other shape, like flat column, prism-shaped etc.; During assembling, make groove 11 on it aim at fixture blocks 24 and be set to and also can play on the connecting head 22 hollow tubular 10 firm purpose of connecting.
The above; Be merely the embodiment of the utility model; But the protection domain of the utility model is not limited thereto, and should be understood that, concerning those of ordinary skills; Can improve or conversion according to above-mentioned explanation, and all these improvement and conversion all should belong to the protection domain of the utility model accompanying claims.
